The following materials are designed to be used in cycles, to link them to your project I recommend to search on goolge append nodetree from library where you can find some tutorial much clearer than how much I can write here in words.

Various infoCell Shading:There are available two different group, the CellShading with dynamic reflections of light but the contour can cause artifacts of aliasing (in particular at slow res/sample), so the advice is to choose a less strong color for the outline; the second one is called CellShading Definitive it haven't dynamic reflections but have a better look for a toon design.

Carpaint:It is not a material with studies behind it, that defines it like physically accurated well but it can give very convincing results.

Glass/Water:By starting preview does not help much to understand the quality but the fluids are excellent (like example figure that you find in gallery), if managed in a way it can also be good as glassy material.

Gemstone (Diamond):This material is useful for diamonds, requires a correct modeling geometry based on advanced edge cut of a gemstone.You can adapt to other gems simply changing the light diffraction (RGB), you need to change it accordingly to specific gem you choose.

Plastic / rubber:This material is very flexible, not as well as possible to be considered physically accurated, in any case it contemplates transparent or solid materials and in both cases it's applicable a consistency (like example in gallery), you can also set a parameter that allows you to exchange/mix by a plastic effect to the rubber effect as needed.

N.B.Remember, the file contains only the preview Balls with materials, the example that you see in the gallery are not included in the file. They are simple examples to show better the material one time you applied them on an appropriet model.

Enjoy :)
